UITextView does not respond to UITextInputTraits Protocol

I have a UITextView in my app and would like to change the keyboard appearance and return key etc. Unfortunately using the UITextInputTraits protocol does nothing to the keyboard which is displayed when tapping the UITextView.

For example I do something like this


myUITextView.keyboardAppearance = UIKeyboardAppearanceAlert;


am I doing something wrong?


Thanks!
